2 OverviewA low-traffic service is generally a delay-sensitive service with a small amount of data. For

example, the PING command, belonging to the BE service, is a low-traffic service. When such

a service is carried on the HSPA channel, the NodeB cannot identifies the service from the BE

services through the service priority and ensure its low delay.

The UMTS network is a radio network whose radio resources are shared by all the UEs in a cell.

When the traffic volume in a cell is high, the QoS of low traffic services is easily impacted by

other services. Generally, users, however, are more sensitive to the delay of burst low traffic

services. Therefore, the user experience decreases obviously. This feature identifies a burst

service based on the traffic features, and then reallocates more resources to it. Thus, more

resources are available for the data transmission of the low traffic service, and the UE obtains

better service delay experience.

Figure 2-1 Overview of low-traffic service monitoring

This feature is implemented in the following procedure: NodeB identifies the characteristics of

services carried on the HSPA channel to find the low traffic services, such as gaming service

and chat service (MSN messenger for example), which have a small amount of data to transmit

each time. Then, improve the capability of services to obtain resources on the basis of the

scheduling and flow control principles of HSPA, thus improving the low traffic service delay

experience.

UEs can obtain good delay experience when they use the services with burst low traffic.

3 Technical DescriptionThe NodeB monitors the HSPA traffic. If the traffic within 500 ms is lower than BurstPacketSize

( DLCOPPERUEBPS , DLGOLDUEBPS , DLSILVERUEBPS , ULCOPPERUEBPS ,

ULGOLDUEBPS or ULSILVERUEBPS ), the NodeB identifies this service as a low-traffic

service.

Figure 3-1 shows the mechanism of low-traffic service monitoring.

Figure 3-1 Mechanism of low-traffic service monitoring

The delay problem of low-traffic service mainly lies in HSUPA scheduling in the uplink from

UE to NodeB and HSDPA flow control in the downlink from RNC to NodeB. The solutions are

described as follows:

l In HSUPA scheduling, the NodeB allocate resources to UEs through absolute grant (AG)

and relative grant (RG). If a UE requests a serving grant (SG) with the increment higher

than the AG threshold, the NodeB uses the AG to schedule this UE.

WCDMA RAN


Feature Parameter Description 3 Technical Description



7


11/21

If the traffic is very low but the AG threshold is very high, the UE can be scheduled only

by RG. As the rate grant given by RG is stepwise, it takes long time for the UE to send its

data, which affects the user experience. To ensure that the small packets from UEs can be

sent rapidly to the NodeB, the NodeB monitors the UEs with low-traffic services in the

uplink and dynamically sets low AG thresholds for these UEs.l In HSDPA flow control, the NodeB allocates bandwidth to services based on the service

rates on the Uu interface and the RLC buffer occupancy (BO). For the low-traffic service,

the service rate on the Uu interface and the RLC BO are very low, and therefore the allocated

bandwidth is very small, which affects the user experience. To ensure that the RNC can

rapidly send data to the NodeB and to reduce transmission delay, the NodeB monitors low-

traffic services and allocates large bandwidth to these services. Considering the possibility

of Iub congestion, there are no more than four low-traffic services which can be handled

by HSDPA flow control.

4.3 Activation

Using MML Commands

l For the DBS3800, BTS3812E, and BTS3812AE

Run the NodeB MML command SET UEQOSENHANCEPARA to set the burst packet

sizes of the gold, silver, and copper users according to the actual conditions.

l For 3900 series base stations, BTS3902E, and BTS3803E

Run the NodeB MML command SET NODEBUEQOSENHANCE to set the burst packet

sizes of the gold, silver, and copper users according to the actual conditions.

Using the CME

NOTE

When configuring the Improvement of User Experience in Low Traffic Service feature on the CME,

perform a single configuration first, and then perform a batch modification if required.

Configure the parameters of a single object before a batch modification. Perform a batch modification

before logging out of the parameter setting interface.

Step 1 Configure a single object (such as a cell) on the CME.

Set parameters on the CME according to the operation sequence described in Table 4-1. For

instructions on how to perform the CME single configuration, see CME Single Configuration

Operation Guide.

Step 2 (Optional) Modify objects in batches on the CME. (CME batch modification center)

To modify objects in batches, click on the CME to start the batch modification wizard. For

instructions on how to perform a batch modification through the CME batch modification center,

press F1 on the wizard interface to obtain online help.

4.4 Activation Observation

Perform the following steps to verify whether this feature has taken effect on HSDPA services:

1. Enable two HSDPA UEs to access one cell.

2. When this feature is disabled or enabled, use UE1 to perform an FTP downloading service

and UE2 to perform a ping service.

3. Compare the ping service delay for UE2 when this feature is disabled or enabled.

If the ping service delay decreases after this feature is enabled, this feature has taken effect on

HSDPA services.

Perform the following steps to verify whether this feature has taken effect on HSUPA services:

1. Enable one HSUPA UE to access a cell.

2. When this feature is disabled or enabled, use the UE to perform a ping service.

3. Compare the ping service delay when this feature is disabled or enabled.

If the ping service delay decreases after this feature is enabled, this feature has taken effect on

HSUPA services.

4.5 Deactivation

Using MML Commandsl For the DBS3800, BTS3812E, and BTS3812AE

Run the NodeB MML command SET UEQOSENHANCEPARA. In this step, set the

burst packet sizes of the gold, silver, and copper users to 0.

l For 3900 series base stations, BTS3902E, and BTS3803E

Run the NodeB MML command SET NODEBUEQOSENHANCE. In this step, set the

burst packet sizes of the gold, silver, and copper users to 0.

NOTE

When the burst packet size of a user is set to 0, it indicates that the NodeB stops identifying the low traffic

services of the user.

MML Command Examples

//Deactivation procedure

//For the DBS3800, BTS3812E, and BTS3812AE

SET UEQOSENHANCEPARA: ULGOLDUEBPS=0, ULSILVERUEBPS=0, ULCOPPERUEBPS=0,
